If you check carefully, some forms are old too. I don't know about this year, I heard people applied in previous years got rejected by using old version forms even they downloaded from the website after the new versions posted. I don't know why that website doesn't always contain the latest information if you saved it in your favourite. You can compare the forms on that website from the ones you click the link in your invitation email, they are different! So are the mailing address! Anyway, certainly you can try to challenge the carrier address. Probably it still will be reached, but I already heard that someone who delivered to that address only got delayed for 3 weeks so far.
